D rings to the floor of my truck, pieces of chain hooked to those, 2 heavy duty carabiners. I put the bike into the truck and lean it a little to one side and put the caribiner through the footpeg, then put my belly on the seat while pushing it away from me and set the caribiner on the other side. It takes me less time to strap down my bike than anyone in my group and my suspension is compressed maybe 1/2 inch if that. You can bomb over anything, drive as fast as you want...stop as fast as you want, the thing never budges with zero compression on anything. Its the exact same set up as that racking system shown but the attachment point is a Harbor Freight $3 D ring.
